Sore boobs?

My breast will hurt almost a week before i start my period but normally stop hurting during my period. I started Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> and had a light maybe 3 day period. Not too uncommmon bc i have been off for 2 years since my miscarriage. But it is now jan 8th and my boobs haven't stop being sore. Had anyone had this problem before?
